Answer 2

Given: Activation energy for forward reaction is 100kJ/mol. Activation energy for backward reaction is -250kJ/mol.

To find: enthalpy change in reaction.

Step-by-step method:

Step 1 of 1

The activation energy for backward reaction is equal to sum of activation energy of forward reaction and enthalpy change.

$E_{b} =E_{f} +$Δ$H$

Δ$H=E_{b} -E_{f}$

Δ$H=-250-100$

Δ$H=-350kJ/mol$.

THE ENTHALPY CHANGE IN REACTION IS -350kJ/mol.
